Clinical Usefulness of Response Profiles to Rapidly Incremental Cardiopulmonary Exercise Testing

Figure 5

Relationship between oxygen uptake and minute ventilation during incremental exercise in a healthy subject and patients with mild and severe (▲▲▲▲) CHF. (a) The slope of upon is the oxygen uptake efficiency slope (OUES) which gives the rate of increase in for a 10-fold rise in . (b) The highest ratio is the efficiency slope (OUEP) which is the average of values just prior to the estimated lactate threshold. Unl is unloaded pedaling.
